Code This Before Your Next Scroll

Produce a beginner-friendly coding lesson for TikTok and YouTube Shorts showing how a simple Python loop prints a countdown. Start with a close-up of a laptop keyboard, filmed at a 35mm lens with a quick slider move, then transition to a neon terminal animation floating beside the presenter. Use magenta-and-cyan studio lighting, sharp screen reflections, and clean kinetic typography. The creator types each line slowly, explains the loop in plain English, and visually highlights indentation with glowing guides. Include a deliberate typo, pause for viewers to spot it, then correct it with a satisfying sound cue. End with a tiny challenge: modify the code to count upward.
